A previous commit changed all of the migration from the old to the new ring for resizing to use READ/WRITE_ONCE. However, ->sq_flags is an atomic_t, and while most archs won't complain on this, some will indeed flag this: io_uring/register.c:554:9: sparse: sparse: cast to non-scalar io_uring/register.c:554:9: sparse: sparse: cast from non-scalar Just use atomic_set/atomic_read for handling this case.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
